To all whom 'it may concern:

Be it known that I, FRANK W. SCHEIER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Flushing Apparatus for Water-Closets; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to fiushing apparatus for water closets, and is an improvement comprising the combination of parts substantially as hereinafter shown and described and more particularly pointed out in the Claims.

My primary object embodies anVair-tight tank open to a constant water supply under pressure, combined with mechanism adapted to regulate the discharge of water from said tank by utilizing the compressed air Within the tank. l

The working mechanism of my device is all mounted upon the outside of the tank thereby permitting the use of a smaller tank than usual, as well as bringing the parts within sight and reach for repairs; although my improved construction is especially well adapted to withstand long usage without break-down or repair.

In the accompanying drawings Figure l is a perspec tive view of my improved flushing apparatus and a water closet bowl connected therewith. Fig. 2 is a sectional view of the tank and the operating apparatus therefor.

Tank -2- is an air tight receptacle preferably made of metal and of a size adapted to hold enough water for practical flushing purposes. All connections with tank -2- are made through its bottom -3-. Thus, at the right of the said bottom is screwed an intake pipe -4- having a bell or cap -5- adapted to check and spread the inllowing water. At the center of bottom -3- is a threaded pipe connection -6- which' has a front extension -7- adapted to provide the necessary connection for closet bowl -8-. At the left of bottom -3- is a vertical pipe -9- extending therethrough with its upper end open and above the possible level of the water when tank -2- is filled to its limit. The lower end of pipe -9- projects beneath bottom 3 and its extreme end forms a seat for valve l0- which in this instance is normally held upon said seat by spring l2 encircling the stem of said valve. However, I wish it understood that any other suitable valve, such as a gravity closing plug valve may be used at this point in place of valve -l0. A pivoted lever 1-1 is linked to the valve casing and extends forward at the side of bowl -8- where it can be grasped and operated by the hand. Now returning to the discharge connection -G-, it will be seen that the upper end thereof provides a seat l5- for weighted valve -l6 and its lower end supports a diaphragm casing -2l-. Valve -16- has a rod 17- passing tlirough guide 18- down to a curved disk '-19- engaged with a fiexible diaphragm -20- within casing -2l. The upper face of diaphragm disk 19- is exposed to the water in tank -2- through pipe connection -6-, and the bottom face of diaphragm -20- is in open communication with chamber -23- of air valve l0 through pipe connections -22-. A small pet-cock or air valve -24- taps pipe connection e22 and is used to regulate the outflow of air from beneath diaphragm 20-, thereby governing the speed of descent of said diaphragm and the consequent closing of weighted valve -I6-.

The operation of the apparatus is as follows-After each flushing of bowl -8-, tank -2- refills immediately because intake pipe 4P- is always open to the supply. At this time valve dlG- is presumably seated; as is also air valve -l0-. I-Ience, as the water rises within tank -2- the trapped air therein is compressed within its upper part until the maximum pressure is reached. The tank may now be caused to discharge its contents; and to this end, hand lever I4- is operated to effect a momentary opening of valve -l0-. This being done, the compressed air in tank 2- is free to pass through pipes Q and -22- to act upon diaphragm -20-. As the exposed area of diaphragm -20- is much greater than that of valve -IG- above, said valve will be suddenly lifted from its seat and the water from tank -2- will rush through connection -6 to the bowl. In the meantime, valve l0- has been seated thereby trapping the air within pipe connection -22- to check the descent of diaphragm -20-, and the resultant closing of valve d6- proceeds in as great a degree as predetermined and regulated by pet cock 24. When valve -lG- seats itself finally, the incoming supply of water to the tank re-establishes flushing conditions.

What I claim, is

1. In a flushing apparatus for water closets, an air tight tank having water intake and outlet connections, a valve for said outlet connection having a pressuure device adapted to operate the same, and a valved air connection between said tank and said device.

2. In a flushing apparatuspfor water closets, a sealed tank `having water intake and outlet connections and a valve for said outlet, a pressure operated device for said valve, air distributing connections between said tank and said device, and a controlling valve for said air connections.

3. In a flushing apparatus for water closets, a sealed tank having a water intake and an outlet and a valve for the latter, a pressure operating device connected with said valve having air and Water communicating connections Witli said tank, and valves to regulate the flow o1 air between said tank and said device and the atmosphere.

4. In a flushing apparatus for water closets, a sealed tank and a water supply pipe and discharge connection therefor, a valve for said discharge connection and a diaphragm operated device for said valve having air connections with said tank, a valve for said air connections and an operating lever for said valve, and a relief valve in said air connections adapted to regulate the action of said device.

5. In a flushing apparatus for water closets, a sealed tank having intake and outlet connections and a valve for said outlet connections, operating and controlling mechanism for said valve upon the outside of the said tank havingr air connections with the upper interior of said tank, and a valve for said air connections.

6. In a flushing apparatus for water closets,v an air tight tank having an intake pipe provided with a water spreading and checking cap, a water discharge connection for saidtank having a valve seat and a weighted valve within the tank, a diaphragm regulator open to said dis charge connection having operating parts connected with said valve, a pipe extending into and open to the interior of said tank, and a valved air connection between said pipe and said regulator adapted to open communication between the top of said tank and said regulator to effect the opening of said discharge valve.

7'. In a flushing apparatus for water closets, an air tight tank open to a constant supply of water under pressure, Ain combination with mechanism adapted to regulate the discharge of Water from said tank, and a controlling device for establishing communication between the air in said tank and said Water discharge regulating mechanism.

In testimony whereof I sign this specification iu the presence of two Witnesses.
